Referring to fig. 1 to 4, the present utility model provides a welding tool and a clamping mechanism thereof, which can clamp and fix a workpiece to assist in welding the workpiece. Moreover, the clamping mechanism occupies less space than the prior art, so that the welding tool can be provided with more clamping mechanisms so as to weld more workpieces.
The present utility model provides a clamping mechanism 1 comprising: a base plate 10 on which a positioning block 110 is provided; a clamping block 120 movably disposed on the substrate 10, wherein a clamping station is formed between the clamping block 120 and the positioning block 110; a driving device 130, which is in driving connection with the clamping block 120, so as to enable the clamping block 120 to move towards the positioning block 110; wherein the movement direction of the driving device 130 is set at an angle with respect to the movement direction of the clamping block 120.
Specifically, the driving device 130 drives the clamping block 120 to move, so that the clamping block 120 moves towards the positioning block 110 to clamp and fix a workpiece in the clamping station. Compared with the prior art, the utility model innovatively changes the movement direction of the driving device without affecting the clamping fit of the clamping block 120 and the positioning block 110, so that the movement direction of the driving device is arranged at an angle relative to the movement direction of the clamping block, thereby reducing the space occupied by the driving device in the movement direction (namely the transverse direction) of the clamping block and reducing the space occupied by the clamping mechanism in the transverse direction.
In one embodiment, the driving device 130 is a cylinder.
Regarding the linkage between the driving device 130 and the clamping block 120, specifically, the clamping block 120 is provided with a first inclined plane 121; the driving end of the driving device 130 is provided with a wedge 131, and one end of the wedge 131 is provided with a second inclined plane 1311; the clamping block 120 is in sliding fit with the wedge 131 through the first inclined surface 121 and the second inclined surface 1311. In the embodiment, the driving device 130 performs a retracting action by utilizing the sliding fit between the wedge 131 and the inclined surface of the clamping block 120, so as to drive the wedge 131 to move along with the driving device 130, so that the clamping block 120 moves towards the positioning block 110. Further, according to the wedge boosting principle, when the inclination angle alpha is 45-85 degrees, the clamping force of the clamping block 120 on the workpiece can be increased.
Further, the base plate 10 has a front side and a rear side, and the base plate 10 further has a slot 101 disposed therethrough; the clamping block 120 and the positioning block 110 are both arranged on the front side surface; the fixed end of the driving device 130 is disposed on the rear side, and the driving end of the driving device 130 passes through the slot 101 to be connected with the wedge 131 located on the front side. In this embodiment, the clamping block 120, the positioning block 110 and the driving device 130 are arranged on separate sides, so that the space on the front and rear sides of the substrate 10 is reasonably utilized, and the position layout of the components is prevented from being bloated; moreover, the driving end of the driving device 130 can penetrate through the slot hole 101 to be connected with the wedge 131, and the wedge 131 is utilized to drive the clamping block 120 to move, so that the normal operation of the utility model is ensured.
Since the clamping block 120 applies a reaction force to the clamping block 120 after clamping the workpiece, the reaction force is prevented from affecting the driving device 130 by the wedge 131; further, the base plate 10 further has a stopper 140 disposed at a side of the wedge 131 away from the clamping block 120; the limiting block 140 is provided with a first guiding surface 141; the other end of the wedge 131 is provided with a second guide surface 1312; the limiting block 140 is in sliding fit with the wedge 131 through the first guide surface 141 and the second guide surface 1312. The utility model utilizes the limiting block 140 to limit the wedge 131, so that the wedge 131 can only move along the movement direction of the driving device 130, thereby counteracting the reaction force generated by the workpiece and preventing the driving device 130 from being influenced by the reaction force.
Preferably, the movement direction of the driving device 130 is perpendicular to the movement direction of the clamping block 120. In this embodiment, the space of the clamping mechanism is saved as much as possible by the arrangement (i.e. the angle between the moving direction of the driving device 130 and the moving direction of the clamping block 120 is 90 °).
In one embodiment, the base plate 10 further has a guide 150, and an active area is provided between the guide 150 and the base plate 10; the clamping block 120 comprises a sliding part 1201, which sliding part 1201 moves in the active area to slidingly engage the base plate 10 under the driving action of the driving means 130. In this embodiment, the guide member 150 limits the movement direction of the clamping block 120, so as to ensure that the clamping block 120 can only move in the direction of the positioning block 110 under the driving action of the driving device 130, and prevent the displacement. The sliding portion 1201 may be in surface-to-surface sliding contact with the base plate 10, or may be in sliding engagement by providing a pulley or the like, which is not limited to this aspect of the utility model.
The guide member 150 includes a frame portion and two bending portions, and the two bending portions are disposed at two ends of the frame portion and are fixedly connected to the substrate 10. The guide member 150 in this embodiment is connected and fixed to the base plate 10 by two bending portions, and forms the active area by enclosing the frame portion and the base plate 10, and the shape of the active area is set corresponding to the sliding portion 1201, so as to better limit guiding.
Further, the clamping block 120 further includes a clamping portion 1202, where the clamping portion 1202 is disposed on a side of the sliding portion 1201 near the positioning block 110; the width of the clamping portion 1202 is greater than the width of the sliding portion 1201. The clamping portion 1202 is in clamping fit with the positioning block 110, and the clamping portion 1202 is wider than the sliding portion 1201, so that the contact area with the workpiece is increased, and the workpiece can be clamped better.
Further, the grip 1202 has an extension; the clamping mechanism further comprises a return spring 160, one end of the return spring 160 is connected with the extension section, and the other end of the return spring 160 is connected with the base plate or the limiting block. In this embodiment, the reset spring 160 is used to perform a reset process on the clamping block 120, so that the clamping block 120 can automatically reset to an initial state under the action of losing the driving effect of the driving device 130, and the workpiece is released and is ready for the next clamping.
Preferably, the opposite ends of the clamping portion 1202 have elongated sections; the clamping mechanism further comprises two return springs 160, one ends of the two return springs 160 are respectively connected with the corresponding extension sections, and the other ends of the two return springs 160 are respectively connected with two opposite sides of the base plate 10 or the limiting block 140. In the embodiment, the elastic acting force is increased through the two return springs, and meanwhile, the condition that the clamping part returns to the original position due to a single return spring is avoided.
The other end of the return spring 160 may be connected to the base plate 10 or may be connected to opposite sides of the stopper 140, and specifically needs to be selected according to actual situations.
The working principle of the clamping mechanism 1 is that a workpiece is placed at the clamping station, the driving device 130 performs retraction motion to drive the wedge 131 to move towards the direction close to the driving device 130, so that the clamping block 120 moves towards the positioning block 110, the space of the clamping station is gradually reduced until the workpiece is clamped, and at the moment, the return spring 160 is in an extending state; when the workpiece is clamped, the workpiece gives a reaction force to the clamping block 120, and the reaction force is counteracted by the action of the limiting block 140, so that the driving device 130 is prevented from being damaged. When the fixing of the workpiece needs to be released, the driving device 130 performs an extending action to drive the wedge 131 to move away from the driving device 130, at this time, the clamping block 120 loses the thrust of the wedge 131, and the clamping block 120 gradually moves towards the wedge 131 under the elastic force of the return spring 160 until reset, so that the fixing of the workpiece is released.
The utility model provides a welding fixture, which comprises the clamping mechanism 1. The welding fixture is provided with a plurality of clamping mechanisms 1, and a plurality of workpieces can be clamped and fixed so as to be welded.
Variations and modifications to the above would be obvious to persons skilled in the art to which the utility model pertains from the foregoing description and teachings. Therefore, the utility model is not limited to the specific embodiments disclosed and described above, but some modifications and changes of the utility model should be also included in the scope of the claims of the utility model. In addition, although specific terms are used in the present specification, these terms are for convenience of description only and do not limit the present utility model in any way.
